Abstract

The aim of this paper is to compare different types of microphone preamplifiers. The authors designed six types of preamps using different technologies (f.ex. based on vacuum tube, transistors, operational amplifiers). Assumed parameters such as input signal, gain, power supply were the same for all circuits. Preamps were tested by objective and subjective methods. Then the authors tried to find out relations between different gain components, electroacoustic parameters, and subjective sensation. The authors did not mean to create commercial devices; just to compare and classify objective and subjective parameters depending on the different types of microphone preamplifier.
